Requirements

Collaboration diagram for Requirements:

Modules
	Application requirements
	Bundles requirements

Detailed Description

The bundles in the <requirement> section of the plugin.xml are started when the bundle is started.

In fw4spl, we can automatically start bundles in two case:

• The bundle contains an AppConfig or an Activity: the bundle will be started when the config or the activity is launched
• The bundle contains services: the bundle will be started when one of the services is used in an AppConfig to launch.

But in some case, we must define the bundles to start manually using the <requirement> tag.

Which bundle should I add in requirement ?

You must add requirement for:

• bundles containing data (ex. dataReg)
• bundles containing registry (ex. servicesReg, activities)
• bundles for preferences, guiQt, visuVTKQt, memory
• ...
